CAR-BU FFER.

SPECIFICATION forming part of Letters Patent No. 659,781, dated October16, 1900.

Application led May 7, 1'900. Serial No. 15,730. (No model.)

To all whom, it may concern:

Beit known that I, HERMAN F. BALL, a resident of Cleveland, in thecounty of Cuyahoga and State of Ohio, have invented certain new anduseful Improvements in Car-Buffers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to improvements in car-buffers. v

The object of this invention is to improve upon the constructiondisclosed in United States Letters Patent No. 604,451, granted to me May24, 1898.

With this object in view my improved carbuffer comprises abuffer-spring-containing case that consists of a section renderedstationary in any approved manner and a blowreceiving section movableendwise of the stationary section and held in its normal and outerposition by the tension of the spring or springs within the case andprevented from outward and circumferential displacement by improvedmeans not requiring bolts and nuts or separate pieces.

The present inventionl consists, therefore, in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure I is a side elevation, in centralVertical longitudinal section, of -my improved car-buffer. Fig. II is anouter end elevation, mostly in section, on line II II, Fig. I. Fig. IIIis an end elevation, mostly in section, on line III III, Fig. I, lookingoutwardly. Fig. IV is a central vertical longitudinal section of thebuffer, showing the manner of assembling the parts. Fig. V is an endelevation in section on line V V, Fig. IV, looking inwardly.

Referring to Figs. I, II, and III of the drawings, a designates thestationary section of the spring-containing case of the buffer. Thesection c is cylindrical in the main and has its inner end provided witha head a', lthat has any suitable number of holes a2 for the receptionof bolts or screws (not shown) employed in securing the said section tothe car or vehicle that is to be provided with my improved buffer. Thesection a is open at its outer end to accommodate the reception by vofthe buffer-case.

the said section of the movable section b of the buffer-case. Thesection b is in the main cylindrical and extends into the section a asuitable distance. The section b is movable into and endwise of thesection a. The section b is open at its inner end and has its outer endprovided with the head b'.

The buffer spring or springs c are interposed between the inner side ofthe head b' of the section b and the opposing or inner side of the heada of the section a. The section a has its outer end portionprovided uponits inner side with four inwardly-projecting corresponding lugs a3, thatare arranged at equalintervals cir'cumferentially of the movable sectionb, and open-ended channels a4 are formed, therefore, between adjacentlugs a3 and exten'dlongitudinally of the sections The section b has itsinner end portion provided upon its outer side with four laterally andoutwardly projecting corresponding lugs b3, arranged at equal intervalscircumferentially of the said section and having their outer ends, asatb2, Fig. I, overlapping and abutting against or engaging the innerends of the lugs a3 of the section a. Each lug b3 of the section bextends such a distance circumferentially of the said section as torender it capable upon turning the section b to the extent required tobring the said lug b3 into registry with a channel a4 of easily enteringthe said channel. The section b is provided externally at the outer endof each lug b3 with a pair of lugs b4 and b4, that extend longitudinallyof the said section b at opposite sides, respectively, of and close to alug a3 from the outer end of the aforesaid lug b3 toward the outer endof the said section b, and have consequently such an arrangementrelative to the intervening lug a3 of the section athat one or the otherof the said lugs b4 and b4 shall abut against the said lug a3, accordingas the movable section b has a tendency to become displacedcircumferentially in the one or the other direction, and the lugs ofeach pair of lugs b4 are arranged also such a distance apartcircumferentially of the section b that they shall be capable uponturning the section b to the extent required to bring the lugs b3thereof into registry with the channels a4 of the section a of easilyentering a channel IOO a4. The sections ct and h have therefore opposingsurfaces (the inner ends of the lugs a3 of the section ct and the outerends of the lugs b3 of the section b) that prevent the outerdisplacement and detachment of the section b from the section a. Alsothe sections a and l) have opposing surfaces (the lugs b4 of the sectionb and the intervening lugs a3 of the section a) that preventcircumferential displacement of the section b.

The springs c are coil-sprin gs arranged one centrally of the other, andat least one of the said springs, and preferably the inner spring,continuously bears outwardly upon the inner side of the head b of thesection b, and thereby causes the lugs b3 of the said section to bearagainst the inner ends of the lugs a of the section d.

Preferably a plate or metallic Washer cl is interposed between the innerends of the springs c and the inner side of the head a of the section a.The said head a", the head b of the case b, and the washer d areprovided with registering holes e for accommodating the extensiontherethrough of a bolt f that is employed in the assemblage of theparts, as shown in Figs. IV and V, and the bolt-hole within the head dis preferably large enough to receive the head of the bolt, that duringthe bolts operation, hereinafter more clearly appearing, bears againstthe outer side of the Washer d. The shank of the bolt j' extends throughthe head b, and a nut f' engages the said shank at the outer side of thesaid head b.

Preferably the head a of the section a is provided at the inner end ofits bolt-hole with an inwardly-facing annular shoulder or seat a5 forthe washer d, that is preferably circular and has its circular edgeeasily fitting within an annular flange or shoulder a6, that is formedupon and internally of the said head and extends around the aforesaidseat 01,5.

The head b' of the section b has its inner side comprising several ribsb5, arranged radially of the head.

The outer buffer-spring is the main or stronger spring and may or maynot bear against the inner side of the head b of the section b in thenormal and outer position of the said section. The inner and lighterspring directly engages and bears against the said head h continuously,as already indicated, and has sufficient tension to normally retain thesaid section b in its outer and normal position.

The assemblage of the parts is as follows: The washer d is introducedinto'the section a, of the buer-case in position against the inner sideof the head a". The springs c are placed within the section b, that isthereupon placed in position at the outer end of the section a, with thelugs b3 of the section b in registry with the channels 0,4 of thesection a, and consequently with the lugs of each pair of lugs b4 inregistry with the one and the same channel, as shown in Fig. V,whereupon the section b is slid into the section a far enough to retainthe section b within the section a. Ihe bolt f is then introduced bypassing it through the registering holes c, whereupon the nut f isapplied and turned in the direction and to the extent required toactuate the section b into the section a against the action of thesprings c far enough to bring the lugs b4 of the section b inwardlybeyond the inner ends of the lugs a3 of the section a, as shown in Fig.IV, so as to accommodate the turning of the sectionb within the sectionct, which turning of the section b is done with facility, and when thesection b has been turned far enough to bring the lugs b3 of the sectionb into line with the lugs a3 of the section a, and consequently bringthe lugs of each pair of lugs b4 at opposite sides, respectively, of alug a3 of the section ct, the nut f and the bolt f are Withdrawn,whereupon the tension of the springs c acts upon the head b of thesection b and results in the actuation of the said section into itsouter and normal position, and thereby completes the assemblage of theparts of the buffer.`

Brieiiy described, my improved buffer comprises, in the main, a casecomposed of two telescoping sections, the one stationary and the othermovable, lugs formed upon the outer end of the stationary section atsuitable intervals circumferentially of the movable section, lugs formedupon the inner end of the movable section and overlapping the inner endsof the lugs of the stationary section, a springwithin` the case andacting to push the movable section outwardly and cause the lugs of themovable section to bear against the inner ends of the lugs of thestationary section, and means for preventing turning of the movablesection.
